Green satin backless mules with a Grinch-like spiky toe and a low kitten heel sound like they would be the most hated shoes of all time, but they are summer's most-wanted accessory, thanks to Balenciaga and a legion of believers. Granted, not everyone will love or understand these very "fashion week" shoes (we expect some green face emojis on our Instagram feed in response). However, the knife mules are so popular that they have sold out everywhere, from Net-a-Porter to MatchesFashion.com. Mary-Kate Olsen recently wore them as a bridesmaid; meanwhile, the influencing likes of Tamu McPherson and Sandra of 5 Inch and Up have been 'gramming them all month long.
Scroll below to see the controversial mules, and let us know whether you love them or loathe them.
